hi everyone!!!

i have a question i would like to ask you guys

my 1s is leaking water into RH cylinder,i noticed when i looked into the radiator and saw that the water was gone,and besides that,the water goes out from the thank under the seat through that little hose.

also i knew the water was going into RH cylinder because when i took out the spark plug it had water in its electrodes.,

so i think three bond sucks,so i took out the head,cleaned both cylinders top and cleaned head an gasket,then i put them back together and gone to ride.


when i came back home,i waited it to get cold and check the water level,and guess what,it was gone again,where?? into the RH cylinder again

so here is my question

do you think i need to replace the head gasket??

or the head is warped??
please tell me waht you think

normaly you can't re-use a headgasket, so yes, buy a new one

you have to check if the head is warped yourself, use a good straight rule. the manual details that, cylinder head warp inspection.

also check that your cylinders are the same height

Don't forget to check your base gaskets. I picked up a 1S with a siezed motor once and when I pulled it down I found that someone had assembled it without base gaskets (just a smear of clear silicone in it's place ) letting water in to the cylender.

base gastkets are ok

so let me go to check head and cylinders

thank you guys

i will let you know waht happens

If it's not 'steamy' out the exhaust, I'd check the gearbox oil level in case it's geting past the pump seals ??

Good luck !

my kr1s was doing the same take the head off an rub it on a flat serfice with fine wet an dry and use a kawasaki head gasket. Mine was filling the header tank an getting in to the left hand cylinder but i did use a pattern head gasket first time round big mistake.
